Remove dead code from rfc2047

* lisp/mail/rfc2047.el (rfc2047-fold-field): Remove dead code.

It's been disabled since 2005, when I made the change with the
following comment.

(rfc2047-encode-message-header): Disabled header folding -- not
all headers can be folded, and this should be done by the message
composition mode.  Probably.  I think.
